Growth durability
3.13× is healthy, but churn and contraction are eating a meaningful share of new MRR. Tightening retention would compound your growth quickly.
Quick ratio ≥ 4 is the durable-growth benchmark. Below 1, you're shrinking despite new sales — the classic sign to stop pouring in leads and fix churn.
